CDMBINATION GAS AND ELECTRIC OUTLET CLAMP.

To all whom it may concern:

Be it known that I, CARL M. \Vmsnnocn, of Milwaukee, \V-isconsin, haveinvented :1 Combination Gas and Electric ()utlet Clamp, of which thefollowing is a spccification.

My invention relates to devices for sccuring electric wires and moreparticularly for securing in place pieces of flexible insulating tubingsuch as are used to cover electric wires at points where they passthrough openings.

The object of my invention is to provide a clamp especially adapted tosecure the flexible tubing at wall-and-ceiling outlets, and moreparticularly at points where the wires are introduced into a combinationgas-and-electric lamp-bracket or chandelier.

My invention consists in providiiig a clamp adapted to secure theflexible tubing directly to the gas-pipe in such cases, and secure twomembers of flexible tubing together in approximately parallel relationin the case of simple electric outlets, in such a manner as to permitthe lengths of tubing being bent at a convenient angle without cuttingor injuring the same.

My invention is best understood from the accompanying drawings, whereinFigure 1 is a longitudinal section through the upper end of a ceilinggas-and-electric fixture, showing the gas-pipe and flexible tubing inelevation and my clamp in position thereon, also in elevation; Fig. 2 isa transverse section through the wires and pipe on the upper side of theclamp, namely on the plane 2; Fig. 3 is a perspective View of one memberof the clamp shown in Figs. 1 and 2, from the inner side.

The reference letters refer each to the same part in each figure of thedrawings.

In Fig. 1 is illustrated a gas pipe a depending from an aperture b in aceiling c, and having a gas-fixture attached to the lower end thereof,only the upper portion of which, to wit, the outer tubing (Z and thecanopy e, is shown. Through the aperture Z) are passed the two electricwires f, covered by flexible insulating tubing to protect them fromabrasion and injury. These Specification of Letters Patent.

wires f are connected at it to the wires 2' of the fixture in the usualmanner.

My clamp comprises two synm'ietrical members 7' of slieetanetal, each ofwhich is formed with three nearly semicylindrical arched portions, towit, the central arched portion l1 and the two side arched portions m;and the latter two arched portions are made at an oblique angle with thecentral arched portion t: so as to permit of the sloping position of theflexible tubing g. This oblique angle is essential to the successful useof the clamp. The two members 7' are secured together by two screws a,which pass through holes 0 disposed between the central arched portionsZ: and the arched portions m as shown, said screws having on their endsnuts 0, located between the arched portions in such manner that they areprevented from turning thereby.

V hen the screws or are tightened up they act first to draw together thetwo members 1' so as to clip the pipe (1 and thus hold the clamp inplace; and then, on further tightening of the screws, the two ends ofthe members j are drawn together so as to clamp the respective tubes toany desired degree of tightness, and it will be seen that either tubecan be loosened and withdrawn or shittcd in position without moving theother, or changing the position of the clamp on the gas-pipe.

In all cases it is necessary that the arched portions of the clamp standat an oblique angle in order to permit the flexible tubing to bendcorrectly and prevent it from bending abruptly and thereby becomingbroken, or bending the wires too abruptly where they meet the ends ot'the tubing, and this clamp makes unnecessary additional devices forsecuring the wires or tubing along the bend oi. the wires.

Having thus described my in\ 'ention, what l claim as new and desire tosecure by Letters Patent is:

A clamp for securing flexible insulating tubing to gas-pipe con'iprisingtwo strips of scmitlcxible material having each three halfsocketsrespectively at the ends and between the ends thereof, adapted toreceive respectively two pieces of flexible tubing in the just theirdistance to variable dimensions of end-sockets and a gas-pipe in theintermesald flexlble tub1ng.- 10 diate socket; the two strips beingdisposed In Witness whereof I have hereunto set my 'in symmetricalrelation; and two fastening hand in the presence of two witnesses.

devices located respectively between the two 0. M. WHEELOCK. end-socketsand the intermediate socket and Witnesses:

adapted to draw the two pieces together at W. SCHULTZ, Jr.,

the respective ends thereof and thereby ad- WV. T. TULL.
